WINDOW-SHADE.

SPECIFICATION forming part of Letters Patent No. 557,771, dated April 7,1896.

Application filed November 26, 1395. Serial No. 570,194. (No model.)

To (tZZ whom it may concern.-

Be it known that I, JOHN G. J. Davrs, a resident of Augusta, in thecounty of Richmond and State of Georgia, have invented certain new anduseful Improvements in indow- Shades; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the artto which it appertains tomake and use the same.

My invention relates to an improvement in window-shades, and moreparticularly to such in which the shade-roller is adapted to be raisedand lowered, the object of the invention being to produce a window-shadeof the class above mentioned which shall be simple in construction,comparatively cheap to man ufacture, which shall be applicable to anywindow, which shall be ornamental in appearance, and which shall beeffectual in all respects in the performance of its functions.

lVith these objects in view the invention consists in certain novelfeatures of construction and combinations and arrangements of parts, ashereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view illustrating myimprovements. Figs. 2, 3, and at are detail views. Fig. is a viewillustrating a modification of the upper roller.

A represents a window frame or casing, to the top of which brackets 1 1are secured for the reception of the journals of an upper spring-rollerB. This roller is made in telescopic sections 2 2 3, so as to make itextensible and readily adjustable to windows of different widths. Thecentralsection orbody portion 3 of the roller B may be made of brass orother pipe and the end sections 2 2 made to fit over the ends of thistubular body portion 3. One end section 2 may be secured to the bodyportion 8 when the device is first manufactured and the other endsection may be left loose, so that it can be moved more or less on thebodyportion 3 to adjust the roller so as to properly fit brackets on thewindowframe to which a particular roller is to be attached. The endsections will preferably be secured to the body portion of the roller bymeans of screws 1. The end sections 2 of the roller B may be made ofornamental brass castings, and each end section may be made in one or inseveral pieces, as desired, or they might be made of wood covered withdecorative metal shells when cheapness of production is desired. Theroller 13 is provided with two shafts 5, one mounted in each end section2, and havingprojecting ends 6 adapted for the reception of key 7. Theprojecting ends 6 of the shafts 5 may be normally covered by removableornaments 6. Springs 8 surround the shafts 5 and are connected,respectively, thereto and to the roller B. Each shaft is made withnotches for the reception of pivoted dogs 9.

Each end section 2 of roller B is made to form a drum 10, on which tapes11 are adapted to wind, one end of each tape being inserted in a slot 12in the respective drums, and each drum is provided with a collar orflange 13 to prevent lateral displacement of the tapes. The lower endsof the tapes 11 are attached to spring-arms 14, secured to abar 15 atpoints near the ends of the latter. To the ends of the bar 15 brackets16 are secured by means of clips 17, for the reception of a springshaderoller 18, to which lattera shade 19 is secured. Pads 20 aresecured to the ends of the bar 15 and adapted to bear against the windowframe or casing and prevent the same from being marred, and to preventnoise which would otherwise be occasioned by the engagement of said barwith the window-frame when the shade is moved or shaken by the wind orotherwise. It will be seen that bar 15 and shade 19 of any desired sizecan be employed. In fact the shade 19 may be even wider than the upperroller B, if desired. The upper roller may be mounted in the bracketsordinarily employed for supporting spring-roller shades and the lowerroller connected therewith without in the least marring or defacing thewindow-frame. In fact no additional devices are aifixed to thewindowframe.

I prefer to cover the bar 15 with shade-cloth of the same color as theshade, so that it will have the appearance of being a part of thelatter, and the tapes 11 will also preferably be made of the samematerial as the shade. A cord 21 will be attached to each bracket 16 onthe shade-rollerbar, by means of which to bodily raise and lower saidshade-roller.

The springs of the upper roller 13 will be so adj usted by means of thekey 7, above referred to, as to be sufficiently stronger than the springof the lower or shade roller that when the shade is pulled down theupper roller will not be aifected. This is a feature of some importancein the construction of window-shades of the class to which my inventionrelates, because the special, and in some cases intricate, contrivancesheretofore employed for this purpose are avoided and the properadjustment of the rollers relatively to each other can be accomplishedby any one.

It is apparent that the lower roller, carrying the shade, can be readilylowered by pulling on either of the cords 21, and that the shade willalways be lowered evenly and without the slightest difficulty.

If a more economical upper roller B be desired than that abovedescribed, it may be constructed as shown in Fig. 5. In this figure anordinary wooden spring-roller is shown, except in this case thespring-barrel 23 is extended entirely through the roller and two springsand ratchet devices are employed. This roller will also be provided withsleeves or drums 24 for the reception of the tapes and with collars orflanges 25 to prevent the lateral movement of the latter.

My improvements are very simple in construction, comprise few parts, andare efiectual in all respects in the performance of their functions.

Slight changes might be made in the details of construction of myinvention without departing from the spirit thereof or limiting itsscope, and hence I do not wish to limit myself to the precise details ofconstruction herein set forth; but,

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination with an upper roller comprising a central section andend telescopic sections, the end sections being provided with spring andratchet devices and tapes secured to and adapted to wind on said endsections, of a bar secured to said tapes and a spring-actuated shadecarried by said bar, substantially as set forth.

2. The combination with an upper springroller adapted to be attached toa windowframe, of a bar, a spring-actuated shade-roller carried by saidbar, a shade attached to said shade-roller, tapes attached to said barand adapted to wind on the upper roller, and a removable device wherebyto so regulate the tension of the spring in the upper roller that saidspring will, at all times, be sufficiently stronger than the spring ofthe shade-roller that when the shade is pulled the upper roller will notbe turned, substantially as set forth.

3. The combination with an upper roller to be attached to awindow-frame, said roller comprising a central bodyportion and adjustable end sections, of a shaft in each end section, each shaftprojecting beyond the end of the roller and adapted for the reception ofa key, a sprin gin each end section, said springs being attachedrespectively to the shafts and the roller, ratchet devices to engagesaid shafts, tapes adapted to wind on said roller, a bar attached tosaid tapes, brackets secured to the bar, a spring shade-roller mountedin said brackets, a shade secured to said shaderoller and cords attachedto the ends of said bar, substantially as set forth.

In testimony whereof I have signed this specification in the presence ofsubscribing witnesses.
